5 Operator This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product. Precautions Warning Do not disassemble, modify (including changing the printed circuit board) or repair. An injury or failure can result. Do not operate the product outside of the specifications. Do not use for flammable or harmful fluids. Fire, malfunction, or damage to the product can result. Verify the specifications before use. Do not operate in an atmosphere containing flammable or explosive gases. Fire or an explosion can result. This product is not designed to be explosion proof. If using the product in an interlocking circuit: Provide a double interlocking system, for example a mechanical system. Check the product regularly for proper operation Otherwise malfunction can result, causing an accident. The following instructions must be followed during maintenance: Turn off the power supply Stop the air supply, exhaust the residual pressure and verify that the air is released before performing maintenance Otherwise an injury can result. Caution After maintenance is complete, perform appropriate functional inspections. Stop operation if the equipment does not function properly. Safety cannot be assured in the case of unexpected malfunction. Provide grounding to assure the safety and noise resistance of the SI unit. Individual grounding should be provided close to the product with a short cable. -4-

6 NOTE Follow the instructions given below when designing, selecting and handling the product. The instructions on design and selection (installation, wiring, environment, adjustment, operation, maintenance, etc.) described below must also be followed. *Product specifications The direct current power supply to combine should be UL1310 Class2 power supply when conformity to UL is necessary. Use the specified voltage. Otherwise failure or malfunction can result. Reserve a space for maintenance. Allow sufficient space for maintenance when designing the system. Do not remove any nameplates or labels. This can lead to incorrect maintenance, or misreading of the operation manual, which could cause damage or malfunction to the product. Precautions on handling *Installation Do not drop, hit or apply excessive shock to the SI unit. Otherwise damage to the product can result, causing malfunction. Tighten to the specified tightening torque. (refer to page 13) If the tightening torque is exceeded the mounting screws may be broken. Never mount a product in a location that will be used as a foothold. The product may be damaged if excessive force is applied by stepping or climbing onto it. *Wiring Avoid repeatedly bending or stretching the cables, or placing heavy load on them. Repetitive bending stress or tensile stress can cause breakage of the cable. Wire correctly. Incorrect wiring can break the product. Do not perform wiring while the power is on. Otherwise damage to the SI unit and/or I/O device can result, causing malfunction. Do not route wires and cables together with power or high voltage cables. Otherwise the SI unit and/or I/O device can malfunction due to interference of noise and surge voltage from power and high voltage cables to the signal line. Route the wires (piping) of the SI unit and/or I/O device separately from power or high voltage cables. Confirm proper insulation of wiring. Poor insulation (interference from another circuit, poor insulation between terminals, etc.) can lead to excess voltage or current being applied to the product, causing damage. Take appropriate measures against noise, such as using a noise filter, when the SI unit is incorporated into equipment. Otherwise noise can cause malfunction. -5-

7 *Environment Do not use the product in area that is exposed to corrosive gases, chemicals, sea water, water or steam. Otherwise failure or malfunction can result. Do not use in an area where surges are generated. If there is equipment which generates a large amount of surge (solenoid type lifter, high frequency induction furnace, motor, etc.) close to the SI unit, this may cause deterioration or breakage of the internal circuit of the SI unit. Avoid sources of surge generation and crossed lines. Prevent foreign matter such as remnant of wires from entering the SI unit to avoid failure and malfunction. Mount the product in a place that is not exposed to vibration or impact. Otherwise failure or malfunction can result. Do not use the product in an environment that is exposed to temperature cycle. Heat cycles other than ordinary changes in temperature can adversely affect the inside of the product. Do not expose the product to direct sunlight. If using in a location directly exposed to sunlight, shade the product from the sunlight. Otherwise failure or malfunction can result. Keep within the specified ambient temperature range. Otherwise malfunction can result. Do not operate close to a heat source, or in a location exposed to radiant heat. Otherwise malfunction can result. *Adjustment and Operation Set the switches by using a sharp-pointed screwdriver etc. It may damage set switches. Perform settings suitable for the operating conditions. Incorrect setting can cause operation failure. For details of each setting, refer to page 14 of this manual. Please refer to the PLC manufacturer's manual etc. for details of programming and addresses. For the PLC protocol and programming refer to the relevant manufacturer's documentation. *Maintenance Turn off the power supply, stop the supplied air, exhaust the residual pressure and verify the release of air before performing maintenance. There is a risk of unexpected malfunction. Perform regular maintenance and inspections. There is a risk of unexpected malfunction. After maintenance is complete, perform appropriate functional inspections. Stop operation if the equipment does not function properly. Otherwise safety is not assured due to an unexpected malfunction or incorrect operation. Do not use solvents such as benzene, thinner etc. to clean the SI unit. They could damage the surface of the body and erase the markings on the body. Use a soft cloth to remove stains. For heavy stains, use a cloth soaked with diluted neutral detergent and fully squeezed, then wipe up the stains again with a dry cloth. -6-

12 1, Communication wiring The network cable and communication connector for CompoNet are connected in the following manner. Note The communication connector for the SI unit should be as shown below. Communication connector SMC OMRON HONDA TSUSHIN KOGYO For flat ribbon cable: IDC connector EX9-CCM1 DCN4-BR4 - For round cable: Terminal block connector EX9-CCM2 - HCN-TB4LMZG+ We do not provide a tool that is used for wiring IDC connector. Please contact OMRON for further details. Connection of IDC connector for flat ribbon cable 1, Cutting of cable Cut the cable vertically. Use a tool with sharp edges such as a nipper to prevent short-circuit, and check there are no whiskers of wire sticking out. 2, Connection of cable Match the cable identification color with the color of the cable and insert the cable. The cover is translucent to make it possible to check the cable reaches the end. 3, Pressure-welding the connector Use a tool (OMRON, DWT-A01) to connect wires. (1) As shown below, place the connector cover so that its center (arrowed part) is at the center of the IDC block of the tool. -11-

13 (2) Squeeze firmly on the DWT-A01 Pliers until the lock on the connector clicks into place. Note Do not pressure-weld the connector cover at the edges. Do not pressure-weld the connector cover at the back of the pressure welding block. Set the connector in the correct orientation. (3) After attaching the cable, confirm that it is properly pressure-welded. -12-

14 Connection of terminal block for round cable 1, Removal of protective coating Remove the protective coating, taking care not to damage the sheath of the internal signal cable. 2, Removal of sheath of signal cable Remove the sheath of the signal cable to a length corresponding to the crimped part of the crimping terminal used. 3, Mounting of crimping terminal Use the crimping terminal for wiring. Do not connect electrical wires which are just twisted directly to the terminal block. 4, Mounting to the connector The available crimped terminal is M3 type. The terminal screws should be firmly tightened to 0.3 to 0.5 Nm. 2. Power supply wiring (Solenoid valve power supply) Connect the wiring for the solenoid valve power supply to the power supply connector (EX9-CP2). Tighten the screw with 0.5 to 0.6 Nm of tightening torque. -13-
